I don't know how accurate it is but an article written in 2020.
translation as follows;
In a statement from the Kenya Wildlife Service, it was noted that sperms from the last male northern white rhino that died last year and three embryos were formed from the eggs of the two surviving females.
Tourism and Wildlife Minister Najib Balala stressed that development is a great victory, emphasizing that the extinction of the species is only a matter of time.
Thanks to the project contributed by scientists and environmentalists from Czech Republic, Germany, Kenya and Italy, the animal rhinos will be reproduced with the application to female rhinos in the coming months.
The last two northern white rhinos of the world, whose names are Najin and Fatu, live in Kenya. The project aims to increase the number of the species to five in the first place.
It's a really deep and sad subject...
Anyway, I really would love to see other rhino species in this game.

but I think the northern white rhinos will really fit this game, it's also an important issue.
